Machining method for proteiform double-side-cavity square long rod part

Abstract

Provided is a machining method for a proteiform double-side-cavity square long rod part. In the cutting machining process of the proteiform double-side-cavity square long rod part, the external constraint in the machining process of the proteiform double-side-cavity square long rod part to be machined is supplemented by making the outline of the proteiform double-side-cavity square long rod part to be completely attached to the outline of a vice fixed jaw used for a clamping machine. A first side cavity is subjected to rough machining to be once cut deep to a size, and a second side cavity is subjected to rough machining through clamping positioning with a combined vice, flattening a workpiece with a pressing plate and clamping the part with a vice, so that the principle that stress exerting on the two sides of the proteiform double-side-cavity square long rod part is even and counteract each other is guaranteed; the defect that the proteiform double-side-cavity square long rod part can not be machined due to bending deformation in the cutting machining process of an inner cavity of the proteiform double-side-cavity square long rod part is overcome; the product machining efficiency and the qualification rate of the proteiform double-side-cavity square long rod part are improved.

Description

technical field [0001] The invention relates to the technical field of cutting processing of deformable square long rod parts, in particular to the technical field of inner cavity cutting processing of deformable square long rod thin-walled parts. [0002] purpose of the invention [0003] It overcomes the defects of high processing strength, low processing efficiency, and unguaranteed part size due to deformation and bending of easily deformable square long rod parts during the cutting process of the inner cavity, and improves the processing of easily deformable square long rod parts. Efficiency and product qualification rate. Background technique [0004] Usually, the processing method of easily deformable parts in double-sided cavity, especially forgings, is to process in layers of 1-2mm in the inner cavity of the part, and after each layer of one side is processed, the part needs to be turned 180 degrees to process the other side, repeated many times Flipping and layer...
